When preparing to install Drupal 7 on a clean linux installation (Centos 7 in my situation), what linux user accounts should be created?
I ask this question because I seem to be having problems with file permissions or ownership when installing new modules with Drush. When I do so I get an error like the following:
... /sites/all/modules exists, but is not writable. Please check directory permissions.
I only have 2 linux accounts on this system, root and myself, and typically run Drush as myself rather than root. I have run 'Drush fp' to fix file permission problems, but this error persists.
So what linux accounts besides root should be created for use with Drupal and what should the user file permissions be? Thanks
